Question 2

In which situation is potential energy converted to kinetic energy?

Accepted Answer

A roller coaster descending from the top of a hill

Answer

A stretched rubber band

Answer

A balloon filled with air

Answer

A stone sitting at the edge of a cliff

Question 3

What happens to the kinetic energy of a basketball as it bounces and eventually comes to a stop?

Accepted Answer

It is transformed into potential energy and then dissipated as thermal energy and sound

Answer

It is stored indefinitely in the basketball

Answer

It all converts into gravitational potential energy only

Answer

It remains constant throughout the bounce

Question 4

Answer

A person running on flat ground

Answer

A car accelerating on a straight road

Question 6

What occurs to a pendulum at the highest point of its swing?

Accepted Answer

It has maximum potential energy and minimum kinetic energy

Answer

It remains at constant energy

Answer

It has maximum kinetic energy and minimum potential energy

Answer

It has balanced energy with equal potential and kinetic

Question 7

Which situation illustrates potential energy being transformed back into kinetic energy?

Accepted Answer

Question 9

Which of the following best describes the relationship between kinetic and potential energy in a swinging pendulum?

Accepted Answer

Kinetic energy is highest at the lowest point, while potential energy is highest at the highest points

Answer

Potential energy is highest at the lowest point and kinetic energy at the highest points

Answer

Both types of energy remain constant throughout the swing

Answer

Kinetic and potential energy are always equal at every point in the swing

Question 10

What happens to the energy of a ball thrown up in the air as it reaches its highest point?

Accepted Answer
